Hi, We have not implemented this in the SODFT module. It's on our todo list.
Is there a reason you are trying to do this ? Are you having convergence issues with the larger basis ?
If you post your complete input file, I can try to help out.

Hi Niri,
ok, I understand. I'm not really having convergence issues, I was just using the vector projection as a speedup. It's a handy tool I got used to utilizing in regular DFT/HF. But I can live without it for SODFT, if it's not yet implemented. Thank you for your offer to help though.
Cheers
Lukas
